Here are the main rules of extra time in a soccer game:
Duration: As mentioned before, extra time usually consists of two halves of 15 minutes each, for a total of 30 minutes.
Start and End: It starts immediately after the end of regular time if the score is tied. The referee blows the whistle to start and end each half of extra time, as well as the entire extra - time period.
Substitutions: The number of substitutions allowed may vary depending on the competition rules. Generally, each team is allowed a certain number of additional substitutions during extra time.
Injuries and Stoppages: If there are injuries or other stoppages during extra time, the referee will add additional time to make up for the lost playing time.
Scoring: Goals scored during extra time count towards the final score. If a team scores more goals than the other during extra time, they are declared the winner.
Penalty Kicks: If the score is still tied after extra time, the game may proceed to a penalty - kick shoot - out to determine the winner, depending on the competition format. During the penalty - kick shoot - out, each team takes turns to take penalty kicks until a winner is determined.
